Namespace: DevExpress.ExpressApp.Web

Assembly: DevExpress.ExpressApp.Web.v24.2.dll

NuGet Package: DevExpress.ExpressApp.Web

Declaration

C#

public static void LogOff(
    HttpSessionState session
)

    session As HttpSessionState
)

Parameters

Name	Type	Description
session	HttpSessionState	A HttpSessionState object, which provides access to session-state values, session-level settings and lifetime management methods.

Remarks

Triggers the XafApplication.LoggingOff and XafApplication.LoggedOff events. You can handle the former to cancel the log off process, and the latter, to be notified when a user has logged off. This static method accesses the WebApplication instance via the session parameter’s “SessionApplicationVariable” key value.
